Title: HySIS & 30 foreign small sats - PSLV C43- FLP - November 29, 2018 (04:27 UTC)
Post by: input~2 on 04/18/2018 10:17 AM
A potential payload for PSLV C42 is SSTL-S1, a 450 kg Earth observation satellite  manufatured and owned by SSTL for Chinese private company 21AT Co. Ltd (via reddit)

NovaSAR-S could also be a co-passenger on this flight. It was supposed to be launched on board C40 mission in January but was delayed for some reason.

NovaSAR-S details:

Mass: 430 kg
Manufacturer: SSTL
Country: UK
Payload: SAR

“We are looking at including 25 to 30 small satellites of foreign customers in the next PSLV launch depending on the configuration. They may total 250 kg,” said Rakesh Sasibhushan, Chairman and Managing Director of Antrix Corporation Ltd, which exports ISRO’s products and services.

Quote
C-42 would have new customers as well as repeat users of the Indian launch vehicle, he told The Hindu. The main load in it from ISRO could weigh around 800-1,000 kg.

Mr. Sasibhushan said the international launch market was “looking very good” and Antrix had sought two fully commercial launches (i.e., without an ISRO satellite) each year from the space agency.

According to this article PSLV C-42 will have 25-30 small satelites onboard with total mass of around 250 kg as well as a primary payload from isro with mass of 800-1000 kg.

We can rule out RISAT-1A due to the lift off mass of 1858kg. The article says primary payload will be between 800-1000 kg. According to isros own manifest however both cartosat-3 and oceansat-3 wont be ready till october/november so unless those satelites are ready ahead of time i dont think it will be them either.

I'm willing to bet the primary payload are two commercial 450 kg satelites (SSTL-S1 and novasar-s) or some satelites we dont know about that isro has in development.

Looks like Centauri I from Fleet is flying on this mission.

http://www.manmonthly.com.au/news/fleet-space-technologies-unveils-launch-partners-first-nanosatellite-launches/

Australian Internet of Things (IoT) startup, Fleet Space Technologies, has today announced launch plans for its first two nanosatellites, Centauri I and II, in 2018.

Fleet Space Technologies has announced that the first of its nanosatellites is under contract to launch with Spaceflight aboard an Indian Polar Satellite Launch Vehicle (PSLV) by Antrix/ISRO. This satellite will establish a global network that will connect the world’s sensors and devices, for free. Just one satellite has the ability to cover 90% of the Earth.

At about 400 kg, that still falls short of the 800-1000 kg description.

As the Commission is aware, BlackSky is under a tight timetable to ship its
Global-1 satellite on July 15, 2018, for a September launch.

Global-1 is on a PSLV flight.
Does this mean that PSLV C42 launch date is pushed to the right into September?

ISRO to develop full-fledged hyperspectral imaging satellite (https://www.thehindu.com/sci-tech/science/isro-to-develop-full-fledged-earth-observation-satellite/article19458651.ece)

Quote
A new set of future satellites called hyperspectral imaging satellites is set to add teeth to the way India is gleaned from about 600 km in space. The Indian Space Research Organisation (ISRO) says it plans to launch a full-fledged niche Earth observation (EO) satellite - called the Hyperspectral Imaging Satellite or HySIS - using a critical chip it has developed.

Quote
About a decade ago, ISRO added another EO niche with microwave or radar imaging satellites RISAT-1 and 2 that could 'see' through clouds and the dark - an important feature useful for the military and security agencies.

Quote
'Hyspex' imaging is said to enable distinct identification of objects, materials or processes on Earth by reading the spectrum for each pixel of a scene from space. The payloads development centre, Space Applications Centre, Ahmedabad, designed the architecture of the chip which was made at ISRO's electronics arm, the Semi-Conductor Laboratory, Chandigarh. The result was a detector array that could read 1000 x 66 pixels.

Quote
ISRO first tried it out in an 83-kg IMS-1 experimental satellite in May 2008. The same year, a hyperspectral camera was put on Chandrayaan-1 and used to map lunar mineral resources. Very few space agencies have such a satellite; a German environmental satellite called EnMAP is due to be launched on an Indian booster in 2018.

A slew of satellites are expected to be launched by ISRO after a dull year of launch mission.

Quote
In October itself, another launch of PSLV C43 is scheduled that will carry HySIS or hyperspectral imaging satellite. The satellite is set to add teeth to the way India is gleaned from 630 km altitude as it will enable the country to see in 55 spectral or colour bands.

Yes.
I see that Gunter has changed his LV assignment for PSLV C43 to the PSLV-CA version.

Am I right to deduce that this is because the primary payload, HySIS, is using the SSB-2 microsatellite bus?  And, even 30 more secondary passengers would not overfill the PSLV-CA payload mass limits to a SSO?

(SARAL also used this satellite bus and was launched to a similar polar orbit, with secondary payloads.  SARAL massed only 346 kg.)

Exactly - the small mass of all payloads is a very strong hint, that the CA version will be used.

Also this might end up being a XL variant rather than a CA variant reason being that a extra 450 kg payload was intended to fly on C42 (Which was supposed to be XL variant rather than CA). If that extra 450 kg payload is included on this mission than this will become a XL variant due to payload mass being too heavy for CA and G variant of PSLV being retired.

HySIS is using the SSB-2 microsatellite bus.  SARAL used the same bus and massed 346 kg.

Gunter (https://space.skyrocket.de/doc_lau/pslv.htm) gives a payload capacity of 1100 kg to a PSLV-CA to SSO.

346 kg + 450 kg = 796 kg

796 kg < 1100 kg by approximately 300 kg.

Unless there are other, unknown-to-us factors that consume over 300 kg of performance, I hypothesize that this launch will use PSLV-CA.

Your forgetting the 31 commercial co-passenger payloads. The 450 kg payload is a single payload that was supposed to go up on C42 mission back in september so it may launch on this pslv instead in addition to the other 31 co-passenger payloads. It should add a few hundred kg to the overall payload mass. Also this mission will involve multiple restarts of the upper stage so they may choose the XL variant for extra safety margin. Two similar missions (C38 in june 2017 and C40 in january 2018) were both XL variants so make of that what you will.

More info on ISRO HySis to be launched by PSLV C43 on November 29 from toi and deccan herald newspapers.

The satellite, which can see in 55 spectral or colour bands from 630 km above the ground, will be used for a range of applications like agriculture, forestry and assessment of coastal zones, inland waters, soil and other geological environments. Being an earth observation satellite, HySIS will also be used by the military for surveillance purpose. The optical imaging detector array chip in the HySIS satellite has been designed by Isro's Ahmedabad-based Space Applications Centre and manufactured by its electronic arm, Semi-Conductor Laboratory, Chandigarh.

The hyspex technology is still an evolving science and has become a new global trend. Hyperspectral imaging combines the power of digital imaging and spectroscopy. It collects and processes information from across the electromagnetic spectrum. Hyspex imaging enables distinct identification of objects, material or processes on the Earth by reading the spectrum for each pixel of a scene from space.

HySIS carries two payloads in visible and near infrared regions of the electromagnetic spectrum. This earth observing imaging spectrometer will operate in the 0.4 to 0.95µm spectral range, will have 55 spectral bands with 10 nanometre spectral sampling and 30 metre spatial sampling. Push-broom scanning mode is the operating mode of this sensor from a 630-km orbit. According to Isro officials, 1000 X 66 pixels were designed to be readout, from both top and bottom directions, using four analog video ports to meet the frame rate requirement.

Metal strapping was used for swiftly transferring integrated charges from image to storage region, in order to reduce image smear. Designs (both at chip and package levels) went through detailed review, before clearing for mask making and package fabrication, by a team consisting of members from Isro's SCL (Semiconductor Laboratory) and SAC (Satellite Application Centre).

HySIS spacecrafts carries the Hyper Spectral Compact Imaging in VNIR (Visible and Near Infrared) and SWIR (Shortwave Infrared) spatial region in 60 and 256 contiguous spectral bands respectively, with 10 nm bandwidth providing 30m spatial resolution and covering a swath of 30 km at 630 km orbit.

According to the previous and latest mission kits it appears that C43 is the first flight of the Higher Performance HPS3 stage which replaces the standard PS3 stage as part of the overall PSLV Higher Performance Project (PSLV-HP).

No that is incorrect. The High Performance PS3 (HPS3) has been around since PSLV C4/METSAT mission back in 2002.

PS3 is to reference the third stage of PSLV and HPS3 is the actual version of PS3 currently in use. But yes i agree it would be less confusing if they just use HPS3 all the time.

Really like and appreciate those curtain raisers they have before each mission!  Some of the best they've had are the previews of RISAT-1, Mangalyaan MOM and the GSLV Mark 3 D1.   In this video, the narrator made a little error, I think( dumb non technical layman here :-[)   He said the PSLV fourth stage has a 'cluster' of two liquid engines. I don't think that's correct. The stage has a twin liquid engine configuration, whereas the first stage of the GSLV Mark 3 has a cluster of two Vikas type liquid engines. I do know there's a difference ;D.  K210, mind giving a very brief definition of clustering?  Just a one time thing :)

The paint used on the external body , is it a special type of paint or the normal paint with industry practise of 1 coat of red oxide and 2 coats of paint ?
Any harm in just giving a coat of red oxide to save labour and money ? Every little bit helps , the competition is heating up.

Clustering is when more than one liquid fuel engine is used on a rocket stage. On PS4 stage of pslv there are two small "PS4 engines" hence it is a cluster of two engines. The largest cluster of engines on any indian launch vehicle so far is only 2 however other countries such as the us and russia have vehicles with 5 - 10 engines clustered on a single stage.

Today's launch of PSLV-C43 will be the 68th launch from Satish Dhawan Space Center and 12th launch of PSLV-CA

HySis will be separated at 641 km around 17 minutes from the launch time, then there will 4 restart of PS4 engine, the restart will happen from 59 minutes from the launch time and the first co-passenger will be separated around 109 minutes from the launch time. PS4 orbit will be lowered from 641 km as all the co-passengers will be separated  at around 504 km.

As has been noted before in previous Sriharikota launch coverage, Sri Lanka doesn't appear on the trajectory map.
Was just thinking the same . So googled a map of sri lanka and the trajectory and it seems the vehicle passes over some part of northern sri lanka.
The omission seems deliberate to avoid controversies.

If you look at the mapping of the NOTAM areas for this launch up-thread, you see that the trajectory (apparently) remains off the eastern coast of Sri Lanka.  The same is true for the other descending-node SSO launches from Sriharikota.  I believe most or all launch threads here for previous Indian SSO launches have the NOTAMs mapped out.

Trajectory is fine but see the same on a map and it does seem to pass over the northern and western parts , no chance of eastern sri lanka.

There is no pattern most of the time. Hindi commentator is speaking advanced hindi that even 90% of hindi speakers wont understand while the english commentator is often at a loss for words or repeating moot points. The english commentary this time around was especially bad with commentator getting many things wrong or just speaking nonsense.

Best to ignore commentary and just watch the launch.

[/quote]

Hmmm, let's try- 4 SLV-3 missions, 4 ASLV missions, 45 PSLV's, 12 GSLV Mark1 &2, 3 GSLV Mark 3

Yah, it adds up to 68, and the number includes the failures, 9 in all( 1 SLV-3, 2 ASLV, 2 PSLV, 4 GSLV Mark [email protected])

Off the top of my head, not bad eh? :D  ISRO doesn't include the off target or sub-orbital injections as failures, as long as the satellite in the mission did function( two after manoeuvering from ground control)  and provide valuable data for at least some time. A couple of those satellites had a brief sojourn in space( Rohini-3, SROSS-3) while others lasted/are still lasting pretty much for their expected lifespan( IRS-ID, INSAT 4CR) or not far from it.

It looks like ISRO is not counting the RLV-TD and the Scramjet launches in the 68 figure, supposedly since no satellite or payload was ejected.

Today's launch of PSLV-C43 will be the 68th launch from Satish Dhawan Space Center

68th launch of what rockets? Only orbital? Orbital and suborbital?

Today's launch is the 68th launch ( both Orbital and Sub-Orbital ) and 67th Orbital launch from Satish Dhawan Space Center.

ISRO's 45th overall launch was a sub-orbital launch that was the first flight and sub-orbital development test flight of GSLV MK-III erstwhile known as LVM3-X carrying CARE module on December 18, 2014.

Here is the breakdown of the launches

SLV-3       -     4
ASLV       -     4
PSLV       -      45
GSLV MK-II   -      12
GSLV MK-III   -       3 ( 1 Sub-Orbital )
-----------------------------------------------------------------
Total       -      68 ( 67 Orbital + 1 Sub-Orbital )

ISRO's 45th overall launch was a sub-orbital launch that was the first flight and sub-orbital development test flight of GSLV MK-III erstwhile known as LVM3-X carrying CARE module on December 18, 2014.


The key with this, as with all ISRO statistics, is the exact wording. They are claiming it as the 68th "launch vehicle mission" from SHAR. So flights, including suborbital test flights, of orbital launch systems. In terms of overall launches from Satish Dhawan, or the Sriharikota High Altitude Range as it was formerly known, this would be closer to the 600th launch than the 68th.

Jonathan McDowell lists 519 suborbital launches across his records of space-going, mesospheric and atmospheric flights (https://planet4589.org/space/lvdb/list2.html). This doesn't include the RLV test launch, so adding in this and the orbital launches gives a minimum count of 587 (137 of which reached space). That's just from a very quick count of one source, so may be missing other launches as well, but the point is, there have been a lot more than 68 launches from SHAR.

This is the second time when ISRO has done 2 launches in a month.

First instance of 2 launches in a month :
--------------------------------------------------
September  8, 2016 --> GSLV Mk II F05 successfully launched INSAT-3DR
September 26, 2016 --> PSLV C35 successfully launched its payloads [ ScatSat-1, 5 foreign and 2 student satellites ] into two different orbits.

Second instance of 2 launches in a month :
--------------------------------------------------
November 14, 2018 --> GSLV Mk III D2 successfully launched GSAT-29 in its second development flight
November 29, 2018 --> PSLV C43 launched HySis and 30 other foreign satellites

In the first instance, the gap between 2 launches in a month was 18 days
and this time in the second instance, the gap between 2 launches in a month is 15 days

So, ISRO has improved its launch frequency and lessened the interval period between two launches in a month

Except for the above-mentioned instances, never before has ISRO done 2 launch missions with the such less overlapping interval between 2 launches not only in a month, but also the launch period stretching to the next month.

ISRO's first 25 launches has taken 30 years from 1979 to 2008. But then next 25 launches has taken only 8 years. It is from the tenure of former ISRO Chairman A. Kiran Kumar, ISRO's frequency of launch mission has gained momentum. So, in the upcoming years, we wouldn't be surprised if ISRO crosses the 100 launches in the next 4 to 5 years or even before.

 ^
Not to nitpick, but actually 5th. Apart from the two you mentioned, there were the launches of GSLV Mark 2 and Mark 3 on May 5/2017 and June 5/2017 respectively.  Less than 3 weeks after the Mark 3, a PSLV with 31 satellites went up on June 23/2017.

 Earlier this year, a GSLV Mark 2( carrying the errant GSAT-6A) and a PSLV with the IRNSS-1I, were launched within 2 weeks, March 29 and April 12 respectively.

 Who would have thought in the late 80's and early 90's, when ISRO was struggling with the ASLV, that it would be one day, launching far more sophisticated vehicles successfully within a few weeks of each other :). You just know that there was a lot of cynicism back then, including calls to cancel the wasteful and failed programme!
